ABSTRACT
Indonesia is still having a digital divide problem, where geographical conditions, installation cost and subscriber fee are becoming major constraints in building Internet infrastructures at remote areas. A Delay Tolerant Network (DTN) technique is used in this research for approaching the digital divide problem. By implementing DTN, communications still can be provided in an extreme environment with intermittent connectivity, large and/or variable delays, and high bit error rate. In this research, a train system was chosen as infrastructures as DTN routers using Wi-Fi. Tens/hundreds/thousands of remote areas are passed through by a train, this makes Internet services proposed having low costs and appropriate for remote areas. The complete Internet services system was successfully designed and implemented. The complete system has been tested already at PT Kereta Api Indonesia Daop 2 Bandung to analyzing averall performances on the actual condition. It is shown that the Internet services system based on DTN proposed can be used for providing connection between remote areas and global Internet network.
